摘要
钴铬合金因其优良的耐腐蚀性、生物安全性以及价格低廉等优势而长期用于口腔金属烤瓷基底冠桥的制作。钴铬合金烤瓷修复体的制作一直以传统失蜡铸造技术为主；近年，选区激光熔化（selective laser melting，SLM）技术因其个性化、精准化以及高效等优势而越来越受到义齿制作中心和临床医师的重视与青睐。本文重点就SLM钴铬合金烤瓷基底冠的制作流程、组织结构、力学性能、金。瓷结合强度、基底冠适合性以及耐腐蚀性和生物安全性的最新研究进展进行综述。
Cobalt-chromium alloys have been applied to dental porcelain fused to metal （PFM） restorations over the past decades owing to their excellent corrosion resistance, good biocompatibility and low price. The production of CoCr metal-ceramic restorations has always been based on traditional lost-wax casting techniques. However, in recent years, selective laser melting （SLM） is becoming more and more highly valued by dental laboratories and dental practitioners due to its individuation, precision and efficiency. This paper mainly reviews the recent researches on the production process of copings, microstructure, mechanical property, metal-ceramic bond strength, fit of copings, corrosion resistance and biocompatibility of SLM CoCr metal-ceramic alloy.
